When can players substitute?

• A. Only during halftime.
• B. During dead-ball stoppages, after goals, or per the rules of the format.
• C. After every scoring play regardless.
• D. Substitutions are not allowed.

Answer: (B)

Substitutions happen only when the disc is not in play. You can bring players on or off during dead-ball stoppages, after a goal, or under any format-specific rules. That’s why this option is the best: it matches the normal flow of play—no substitutions during live points, but you can switch players between points (after a goal) or at halftime, and some formats may allow additional windows (like after timeouts or injuries). The other choices are too limiting or too broad: halftime-only misses the common post-goal substitution opportunity, and saying you substitute after every scoring play isn’t guaranteed across formats.
